This is very true. I think the distinction is consent, and choosing who you give up privacy for. When I visit a web page, I don't know whether the page is going to track me or not. By the time I find out, it is too late, my visit has already been recorded. When I give a publisher/content-creator/whatever money, I am agreeing to enter into a transaction with them, and I expect that they will have a record of that transaction.

makes sense

I wonder if this whole "front-end" blocking will just push things to the back-end.

How long until websites start sharing back-end tracking data between themselves?

I have heard anecdotal stories about companies being asked to put reverse proxies on their networks in order to make the ads "first-party." Seems like that will be the next step in the arms race.

Well, I guess we will have anonymous payment systems for that. Bitcoin (although very trackable) is already a start in the right direction.
